What are the defects in insulin and effects on glucose metabolism?

---

For example: What’s gone wrong with insulin production and how does that affect the body’s ability to fuel itself with glucose (blood sugar)? Please explain for type 1 and type 2!
Insulin is needed so that the cells can utilize the sugars in your blood for energy.
Type 1 is because your body does not manufacture enough or any insulin.
Type 2 is that your cells do not react correctly to the insulin and therefore do not use the sugar in the blood correctly. AKA Insulin resistant.

The pancreas stop producing insulin when the body's own immune system attacks and destroys the insulin-producing beta cells of the pancreas. Therefore, it is an autoimmune disease.
Destroyed cells will not ever make the hormone insulin again.

It has not been established yet, as to why this happens. However it is thought to be in connection with genes, though having the right gene is not enough.  (+ info)

How common are thyroid or other metabolism slowing disorders?

---

Everytime I read articles about weight/obesity in America many of the posters indicate how common these disorders are. I'm just truly curious how common is common. Do 1 in 100 suffer from these types of problems or is it more like 1 in 1000? Are there other medical conditions that cause weight gain?
Hi from Mr J. Yes they are very inportant to are body, because they play a inportant roll in ower live hormons, that comtrols the cortazone that make as get fat by have a lot of it, or thin if we have very little in ower body, so see your Dr to ask for help.  (+ info)

Which organ doesn't require insulin for metabolism of Glucose in it?

---

Is it brain? Brain utilizes Glucose but I don't know its perfect mechanism. Does it need insulin for its metabolism?
So back to the main question, which organ doesn't require insulin for metabolism of Glucose in it?
well, actually..insulin is a substance that converts glucose into glycogen..Its secreted by the pancreas whenever there is a high glucose concentration in the hepatic portal vein..  (+ info)

How common are thyroid and other metabolism slowing disorders?

---

I've seen these disorders listed as reasons for weight gain and inability to lose weight and wanted to know how common they truly are. I do not have any of these conditions, I'm merely curious about whether they are as common as they seem.
I should have been specific. I'm looking for statistics. Ball park will work. Do 1 in 100 folks in the US suffer from these things or is it 1 in 1000?
The prevalence of thyroid disease in the United States is 1 in 13.

Additionally, it is estimated that another 1 in 20 have undiagnosed thyroid disease.

Unfortunately, seven times as many women get thyroid disease as men, so it is nearly impossible to obtain good treatment for thyroid disease. That is, if you can even get tested and get a correct diagnosis.

One in eight women will get thyroid disease during their lifetime.  (+ info)

How can I lose weight after suffering from Eating Disorders and with a slow metabolism because of them?

---

I had anorexia for a few years and more recently I've suffered from bulimia and binge eating disorder. As a result of the binges, I put on 3 stone (42 lbs) in about 3 months.
I've since stopped binging and now eat around 1600 cals a day from healthy sources (lean protein, good/wholegrain carbs and plenty of fruit/veg) and exercise on a daily basis - exactly what the dietician told me to do. However, my weight is still going up and it's driving me insane being this big AND not being able to lose weight or even understand why I'm still gaining.
I know there are issues with the metabolism n muscle weighing more that fat, but I'm not even seeing a difference in my clothes sizes etc.
Please help - I have become severly depressed because of my body and I can't take this for much longer. I still have regular counselling sessions but it's got to the point where there is little that they do for me

Thanku in advance
I don't mean to be disrespectful, but I don't believe you are eating only 1600 calories a day and still gaining weight, unless you are being very sedentary. Metabolism varies in people, especially if there is a pathological reason for it such as thyroid disease. However, if you're burning more calories than you're taking in, you will lose weight. That is a physiological fact. Do you write down what you eat? Having been anorexic, you're probably very aware of the calorie count of everything you put in your mouth. Sometimes seeing it on paper, though, helps you determine where you may be going wrong in your eating.

Have you had a physical recently? Is your thyroid ok? What do you consider exercize? Is it enough to get your heart beating more quickly and all your muscles working?

Perhaps you need medication for your depression. There are so many new, effective medications for depression that can help you through this difficult period and improve your motivation and frame of mind. Perhaps you need a new counselor, if you've reached a plateau with this one.

Don't give up. Be honest with yourself and remember that it will take time to get your body back into shape.  (+ info)

What dietary supplements are good for Glucose metabolism?

---

I've heard of cinnemon.. Is there a better one, i'm pre-diabetic.
Cinnamon is really good. You could also try chromium picolinate. I've also heard of something called bitter melon, although I've never tried it myself. There's a multivitamin called Alpha-Betic that has a bunch of different glucose metabolism supplements in it..it's a BIG pill though! lol I think you're probably talking about type 2 diabetes, and if that's the case, one of the most effective thing you can do is exercise, even if just a little bit. Good luck!  (+ info)

hyper and hypo metabolism in people with eating disorders?

---

i know that people with anorexia slow down their metabolisms. but then their metabolisms get amped up when they start eating? how does this work and why?
i had bulimia and anorexia and now am trying to eat normally and my metabolism is 1300.
Is this incredibly slow? Other anorexia patients have very high metabolisms-talking about 3000 here! Please explain the whole thing if possible?
thank you so much!
And is my metabolism very very slow?
When a person is eating too few calories, the body is doing everything it can to conserve energy. Therefore, when the person with anorexia is starving, the body's metabolism is slowed, but when the person begins to eat again, the body has to rebuild tissue, and all of the systems within the body have to work extremely hard to get the person healthy again. All of this takes a lot of energy and results in the person having a higher metabolism or even becoming hypermetabolic.
If you found out that your metabolism is 1300 from an online calculator or any formula, chances are that it's not a correct calculation. If, however, you've discovered that your metabolism is 1300 by consuming 1300 calories per day and maintaining weight, then that's probably correct. However, generally the more calories you consume, the higher your metabolism becomes. You could probably consume more than 1300 calories per day and maintain weight. If you need to gain weight to become healthy, you'll need to eat more than that, and your metabolism may become extremely high. By allowing your body fewer calories than it needed, you probably slowed your metabolism down, but when your eating patterns stabilize and you head towards healthier eating, your metabolism may change.
I hope that this answer helped, and good luck with your recovery.  (+ info)

Can Glucose tablets potentially increase a person's metabolism?

---

If you are not diabetic, can taking glucose tablets increase someones metabolism since they increase a person's energy level..etc.
It is the same as eating the same amount of table sugar; too little to do much. Besides, sugars don't increase your metabolism, they are fuels for energy metabolism.  (+ info)

Which event occurs in the cytoplasm of a cell undergoing glucose metabolism?

---

glycolysis  (+ info)

how does glucose metabolism demonstrate a homeostatic mechanism?

---

help!
The homeostatic mechanism governs glucose metabolism. Glucose metabolism demonstrates the homeostatic mechanism in its regulation of the glucose fuel supply to the central nervous system.  (+ info)
